Soybean and Wheat Response to Cropping and Tillage System After Two Decades in an Oxisol

Abstract: -No-tillage system have been a mainly conservationist system specially in tropical and subtropical climate conditions. The aim of this work was to evaluate yield components and morphological soybean and wheat in Rhodic Eutrudox under tillage and cropping systems in Subtropical climate (Londrina, Brazil, latitude 23º11'S; longitude 51º11'W; and 620 m in altitude). This study was carried with five tillage and two cropping systems, on completely randomized block design, with four replications. Tillage systems con… Show more

“…Therefore, reduction of macropores in compacted soil affected soil aeration, which affects root growth and grain yield. In a long-term experiment in an Oxisol soil, chiseling reduced the yield grain of soybean (Moraes et al, 2017b). Thus, in loose soil, the main factor to reduce the yield and root length density should be due to the reduction of plant-available water capacity ( Figure 4 ) promoted by reduction of size and stability of soil aggregates (Nunes et al, 2015) in chiseled areas.…”

“…Soil conservation systems, which leave crop residue on the soil surface, include MT (using scarifiers) and NT (Dam et al, 2005). NT is based on the application of a set of technologies to avoid soil disturbance, the permanent maintenance of soil surface with crop residue and crop rotation (Moraes et al, 2017). Its worldwide use is increasing because it results in faster and more efficient operations, in addition to improving soil physical conditions for better crop development and growth (Tavares Filho et al, 2012;Pereira et al, 2018a).…”

“…The effects of soil turning vary, with crops responding differently in terms of grain yield (Moraes et al 2017;Pereira et al, 2018a). To better understand and analyze the spatial behavior of soil and plant properties, geostatistics is used to detect the variability and spatial distribution of the properties, by constructing maps considerin 2014; Bet increase ag conditions componen 2.…”

“…Neste sentido, destaca-se o problema da compactação do solo que, além de aumentar sua resistência à penetração das raízes (MORAES, 2017) limita a profundidade e volume de solo explorado pelas raízes em busca de água e nutrientes (FRANCHINI et al, 2017), reduz a porosidade total, a macroporosidade, a aeração (MORAES et al, 2016a), interferindo diretamente na capacidade de infiltração de água e sua condutividade hidráulica (SILVA et al, 2009). Como reflexo, safras agrícolas tornam-se susceptíveis ao excesso ou deficiência hídrica, o que pode culminar em redução da produtividade das culturas (FRANCHINI et al, 2017;MORAES et al, 2017).…”
